1. Whatever happened, happened. The timeline has not changed at all. The point of the time travel was to detonate the bomb. The purpose of this was not to change the timeline.
2. Widmore said a war is coming. He said this in 2007 time so the war happens further down the timeline than we have seen so far.
3. Jacob said there is only one end and everything else is progress. So changing the timeline isn't as important as winning the war.
4. Detonating the bomb does something to the energy pocket(dark shirt man's power source?) to give Jacob's side an advantage in the future war. It did nothing to change events between 1970's and 2007.
5. 1-4 are way cooler than "oh look we changed the timeline and now everything is just peachy."
I think at the very end we see Jack's eye open when he wakes up back in the future where he and the other losties are back and ready for the war and a kickass final season.
Additionally, on another theory someone wrote that Locke/man in dark shirt told Richard to tell time-skipping Locke to give Richard the compass so that Locke would become leader and so on. Does this violate any rules of combat between Jacob and the man in dark shirt? It seems like taking a direct hand in events instead of merely attempting to influence them. It seems like he cheated to create the loophole to kill Jacob which may be key to giving Jacob the upper hand in future.
